docker

I was running an unprivileged LXC and converted it to a privileged one (backed it up and then restored with it set to privileged) and now I have issues with Apparmor. My main problem is starting a Docker container ~/pihole$ docker-compose up Creating network "pihole_default" with the default...

proxmox ve: 6.2 lxc template: centos-7-default_20190926_amd64.tar.xz CT config: doocker info: I try an image of nginx to run a container, everything is right. But when I try to install k8s on it. the image of kube-proxy can't be pulled, but the other images are no problem I try other...

I’m running Proxmox and a VM with a minimal debian OS. Everything worked fine until I installed docker and Portainer. Well, docker, Portainer and my containers work fine. But now my Proxmox is not accessable, not by GUI and not by SSH. I’ve read that docker could break the bridge as it uses...

Hallo zusammen, wir sehen mit unserem kleinen B2B SaaS gerade etwas Wachstum und ich wollte unsere IT Infrastruktur modernisieren. Ein Freund mit wesentlich mehr Traffic schwört seit Jahren auf Proxmox, deswegen wollte ich mir das mal im Detail anschauen. Kubernetes hatte ich mir vor Jahren zu...

Hi guys, Sorry to bother, but I got perhaps a fairly easy problem, but I can't seem to be able to solve it. I have 1 host with 3 VMs, all of them can reach Internet and resolve domain names, but Docker containers running on said VMs can't resolve DNS (ping google.com fails), but can reach...

Hello, a few days ago we had the problem with several VMs(qemu) that after some time they don't connect to the internet anymore. After some searching, we found out that Docker changes the network configuration(initially set by cloud-init) by itself (the server doesn't have an IPv4 address...

Hallo, vor ein paar Tagen haben wir bei mehreren VMs(qemu) das Problem gehabt, dass diese nach einiger Zeit keine Verbindung mehr zum Internet haben. Nach ein bisschen Sucherei haben wir herausgefunden, dass Docker die Netzwerkkonfiguration ändert und damit zerschießt.(Der Server hat dann keine...

Hi, recently i've added overlay2 module to proxmox-host, so i can easily use basic docker-cli functionality inside an lxc containers (pull/tag/push), without using runtime. But attempt to restore a container with overlay2 layers (docker images) inside fails: extracting archive...

I've had this problem for a while here now, and I've turned the internet upside down trying to figure it out, but there is very, very little information out there about this specific warning. It is extremely consistent and reproducible in my PVE setup though, so I figured I'd ask here! May 28...

Hi, I have a docker swarm stack to deploy, needs to be HA, so my search ends up with a 3 Proxmox server in cluster + Ceph cluster solution(diagram in attach). Each node will have VM with docker swarm running: 2x EMQ X brokers - 2 cores 16GB RAM each (4 cores 32GB RAM) InfluxDB...

I got my hands on a Mac Pro 2012 with two 6 core Xeons. The Mac has a 500GB SSD and three 6TB drives. When I have installed Proxmox previous, I also would install docker and zfs as well. How does setup my data drives to allow both LVM-Thin and docker storage to co-exist or should I just create...

Hi, in the process of automating LXC Docker container installation I came across a problem that makes the container fail to start Docker after restoring a snapshot of the container. Basically I want to setup Docker inside a LXC container and deploy several images using Ansible. I tried to break...

Hi, The other day I stumbled upon gvisor, which is a Google container driver which can be used with Docker that apparently uses an approach which is "mostly user-mode"; it emulates a Linux kernel in usermode, so it might be a way to run Docker containers inside an LXC container without nesting...

I was able to setup Alpine 3.10 to run Docker daemon and run hello-world container in it. Here are the steps. create container based on alpine-3.10-default_20190626_amd64.tar.xz (disk of size 0.5GB is enough for this little test) under Options enable Features 'keyctl' and 'Nesting' start the...

Hi, i have some kind of legacy setup, which i created with Proxmox 5: I have a bunch of LXC containers which are privileged. Inside the LXC containers, i have installed a docker, and some docker containers. The networking of all this is managed by a VM with OPNsense. This worked fine with...

As others on this forum we've been considering for a while migrating some installations to docker containers and also like other I would hope to be able to do it within the Proxmox setup. I was wondering if the new Proxmox 6 brings any updates or changes to this. As far as I understand Proxmox...

I'm considering running docker (and some docker containers) off of proxmox and wondered whether running docker inside an LXC or a VM would be better? I noticed from the following URL that it mentions that running docker in a VM would be better but gives no reason why this would be the case...

We have a small vSphere cluster in our lab but we're increasingly using Docker. This however isn't ideal since we'd like a GUI managed solution which natively supports Docker (like Synology's DSM). Does Proxmox have Docker support in the web interface? I see mention of it in 5.3 but I can't...

I upgraded from 5.2 to 5.3 and am trying to re-deploy self service unprivileged containers where users create an LXC container and then can do whatever they need to do (mostly installing docker, mounting file systems etc) First I am disabling all the magic hacks that were required to run docker...

Hi, I'm toying with running Docker inside a CentOS 7 LXC on a Proxmox whose storage is ZFS. The container has: $ cat /etc/pve/lxc/209.conf ... features: nesting=1 ... and is a privileged container. For starters, the only storage driver that allows me to start the Docker service is vfs. ZFS...
